BeachChessAn Indiegogo campaign has been launched for Beach Chess, which consists of one white cube and one black cube. Each of the cube’s six faces features an outline of each of the six unique chess pieces—pawn, rook, knight, bishop, king, queen.

Each cube measures about 2.5 inches square and fits in the hand. The black cube makes a fully depressed imprint in the sand, whereas the white cube only makes an outlined imprint so you can tell the difference between the “white” and “black” pieces.

To play Beach Chess, players draw the board with their finger, and then line up pieces by using the block to make imprints. Whenever anyone wants to move a piece, they make a new imprint where they want it to go, and use the cube’s edge to wipe away the previous imprint. Players register captured pieces by the side of the board.

The campaign is attempting to raise a total of $9,000 to create the first 360 sets, at a cost of $25 per set. If the campaign, which closes on May 14 at 11:59 p.m. PT, achieves its goal, there will be an online store dedicated to continue selling the game.

More information on Beach Chess and contributing can be found at the campaign’s Indiegogo page.
